Are RNAs processed before translation is able to occur in Prokaryotes? Do only mRNAs undergo processing and maturation in Eukaryotes?
Answers
Answer: RNAs are not processed before translation in prokaryotes, this process only takes place in eukaryotes.
Explanation:
Messenger RNA or mRNA is a single-straded ribonucleic acid that transfers the genetic information from the DNA (deoxyribonucleic acid) molecule of the cell nucleus to a ribosome (which are the machinery responsible for protein synthesis) in the cytoplasm. mRNA determines the order in which the amino acids of a protein will be joined and acts as a template or pattern for the synthesis of that protein. To accomplish this, the DNA molecule must be transcribed into an RNA molecule, which is used for protein synthesis.
The messenger RNA obtained after transcription is known as primary transcribed RNA or precursor RNA or pre-mRNA, which in most cases is not released from the transcription complex in a fully active form, but in eukaryotes it must undergo modifications before it can perform its function (RNA processing or maturation). These modifications include:
Elimination of fragments (splicing): In most cases, the mRNA undergoes the removal of internal, non-coding sequences called introns, and the connection of exons. This does not occur in prokaryotic cells, as they do not have introns in their DNA.Protection by CAP: Addition to the 5' end of the structure called "cap" or "capping", which is a modified guanine nucleotide, 7-methylguanosine triphosphate, via a 5'-5' triphosphate linkage, instead of the usual 3',5'-phosphodiester linkage. This cap is necessary for the normal RNA translation process and to maintain its stability. Polyadenylation signal: Addition to the 3' end of a poly-A tail, a long polyadenylate sequence, whose bases are all adenine. Its addition is mediated by a sequence or polyadenylation signal (AAAAAA), located 11-30 nucleotides upstream of the original 3' end. This tail protects the mRNA from degradation, and increases its half-life in the cytosol, so that more protein can be synthesized.The mature mRNA (in eukaryotes) is transferred to the cytosol of the cell through pores in the nuclear envelope. Once in the cytoplasm, ribosomes are coupled to the mRNA. However, in prokaryotes, ribosome binding occurs while the mRNA strand is being synthesized. After a certain amount of time, the mRNA is degraded into its component nucleotides by ribonucleases. So, the transcription and translation processes are carried out in a similar way as in eukaryotic cells but they occur simultaneously. But, the fundamental difference is that, in prokaryotes, the messenger RNA does not undergo a maturation process and, therefore, no cap or tail is added and no introns are removed. Moreover, it does not have to leave the nucleus as in eukaryotes, because in prokaryotic cells there is no defined nucleus.
So, RNAs are not processed before translation in prokaryotes, this process only takes place in eukaryotes.

Read the following passage from the Biology Department at University of California, Berkeley.
Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
Which of the following best describes how the population has evolved?
The population has not evolved because there was no change in allele frequencies.
The population has not evolved because it has grown.

According to the passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
What is population?The term population reffered to the total number of people living in a particular given area.The population of an organism can't survive if it exceeds it's carrying capacity.
The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase.
If animal population increases the population that eat that animal might also increase.
The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease.
When predictors became scarce due to over population, the weekar species of animal start or die in other ways .
The accurate description of the growth of a natural animal population is limited by environmental factors.
Therefore,The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.

In this assignment, you will use simulations to analyze how climate, resources, and habitat size affect
carrying capacity. You will then look at another simulation to analyze the effects of certain factors that
affect biodiversity and populations. Finally, you will write and revise a conclusion on how human activity
affects biodiversity
Answers
Answer:
Directly affects.
Explanation:
Climate, resources, and habitat size directly affect carrying capacity of an ecosystem. Favourable climatic and environmental conditions increases the population of organisms to its maximum limit. More resources leads to increase in population of species in an ecosystem until carrying capacity. Habitat size also depends on carrying capacity which means higher carrying capacity can leads to bigger habitat size. Climatic change, Habitat destruction, introduced and invasive species and genetic pollution are factors that effect both biodiversity and population. Human activities causes pollution, destruction of habitat by cutting trees etc affects biodiversity.
When a scientist uses radiometric dating to determine the age of a rock specimen, would he use a radioactive element with a short half life, say a half-life of less than 10,000 years, or a radioactive element with a long half-life, say a half-life greater than 1 billion years?
Answers
Answer:
He will use a radioactive element with a long half life of greater than 1 billion years
Explanation:
Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.
According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."
The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.
